need for a simpler way to determine upload size is the main reason I
decided to use quixote 1.x instead 2-alpha when our site (douban.com)
was launched in march 2005. today we're still with 1.x.

by the way, talking about current state of Quixote, douban.com is now
getting 450,000 page views a day. 100% dynamically generated by qx. I
might be wrong but, it seems we are a busier site than every other
known ROR/django/TG installations in the world.

at least i'm reporting in as one happy user.
